Rich Phone Features and SIP Compatibility
The Cisco® SPA512G 1-Line IP Phone with 2-Port Gigabit Ethernet Switch provides
advanced voice and data communications features small businesses need to stay
productive and responsive. Based on Session Initiation Protocol (SIP), the Cisco
SPA512G (Figure 1) has been tested to ensure complete interoperability with
leading voice over IP (VoIP) equipment from voice over IP infrastructure leaders,
enabling service providers to quickly roll out competitive, feature-rich
services to their customers.
With hundreds of features and configurable service parameters, the Cisco SPA512G
addresses the requirements of traditional business users while building on the
advantages of IP telephony. Features such as easy station moves and shared line
appearances (across local and geographically dispersed locations) are just some
of the many advantages of the SPA512G.
Stylish and affordable, the Cisco SPA512G IP Phone can also be used with
productivity-enhancing features such as VoiceView Express, and Cisco XML
Applications when interfacing with Cisco Unified Communication 500 Series in
SPCP Mode.

Secure and Easy to Manage
The Cisco SPA512G was designed to simplify installation, while providing
enhanced security for complete peace of mind. It utilizes standard encryption
protocols to perform secure remote provisioning and unobtrusive in-service
software upgrades. Secure remote provisioning tools include detailed performance
measurement and troubleshooting features, enabling network providers to deliver
high-quality support to their subscribers. Remote provisioning also saves
service providers the time and expense of managing, preloading, and
reconfiguring customer premises equipment.
